Weekly summary should update with current time

[helblinglilly]

At the moment, that component only uses the API repsonse to work out how many hours have been worked this week and how many hours should have been worked.

It has no concept of current time, meaning the only way to update it at the moment is to retrigger the API request being sent which is inefficient.

It should be able to understand when the API response is from, take the current time and whether the user is currently on the clock to make up the difference.
